embodiment 1

Only the RS in the Measurement Slot (Only the SS is Configured)

[0051]FIG. 1 illustrates a measurement slot according to an embodiment of the disclosure.

[0052]Referring to FIG. 1, a measurement slot. In the beam sweeping slot, the gNB TX transmits beams each including the BRS while sweeping the beam in sequence. While the gNB is TX sweeping, the RX receives a specific beam and measures the BRS. Alternatively, when the gNB TX repeatedly transmits a beam including the BRS, the UE may sweep the RX beam. This method applies to the case of RS source variations proposed herein and to the case of in-sync determination. In any case, the term during which measurement can be performed for all combinations of TX beams and RX beams is referred to as term 1, and the specific time below can be multiple terms.

[0053]A. [Calculation for each pair of 1 TX beam and 1 RX beam] counting the values in different terms separately: when the N best measurement values among the measurement values for all TX-RX...

embodiment 2

esent in the Scheduled Analog Beam in Addition to the Measurement Slot (the CSI-RS is Configured)

[0061]In this case, information on the RS resource location at the scheduled TX beam should be shared in advance.

[0062]FIG. 2 illustrates a case where a measurement value for a beam scheduled in addition to the measurement in the measurement slot is added as a sample for a given time duration according to an embodiment of the disclosure.

[0063]Referring to FIG. 2, for a given time, the measurement value for a beam scheduled in addition to the measurement in the existing measurement slot is added as a sample. In the remaining part, the above cases (A to H) described in the first embodiment are directly applied. The measurement value for the scheduled TX beam and associated RX beam and the measurement result for the BRS are added to the case of the first embodiment. When performing the calculation, the measurement value for the added pair of the TX beam and RX beam is added to the previous ...

embodiment 2-1

the RLM Target

[0075]More specifically, the received signal strength of the xSSs transmitted by one beam is referred to as “reception strength of the per-beam xSSs”. Here, the reception strength of the per-beam xSSs may be the average of reception strengths of the xSSs transmitted by one beam, a linear combination of reception strengths with specific weights, or an implementation-dependent value. To issue an out-of-sync (OOS) indication, the terminal determines whether the reception strength of the per-beam xSSs is greater or less than Q_out in consideration of all xSSs transmitted during T_out. If the reception strength of the per-beam xSSs is less than Q_out for all beams transmitted during T_out, the terminal issues an OOS indication to the higher layer. As another example, the network may set the value of N separately to issue an OOS indication if the reception strength of the per-beam xSSs is less than Q_out for N beams. Here, as the number of beams carrying the xSS may be diffe...

Abstract

A communication method and a system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for internet of things (IoT) are provided. The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, etc. The method includes receiving a radio resource control (RRC) message including first information associated with a reference signal for a radio link monitoring (RLM) and second information associated with a threshold for the RLM, monitoring a radio link quality of at least one reference signal indicated by the first information, comparing the radio link quality of the at least one reference signal with the threshold and indicating an in-sync or an out-of-sync to a higher layer of the terminal based on the comparison result.
